Venusaur Problems??

[snowslide12]

I have a Venusaur that I want to use in the Random Match up in Pokemon White. However, it tells me that there is a problem with it (yes, I checked, it IS the Venusaur, not another Pokemon). Does anyone know why it isn't allowed in random match up? It is:
Modest nature
508 evs- 252hp/252spat/4spe
sleep powder/growth/giga drain/hidden power
chlorophyll ability
I made it in Pokegen just like all the other legal pokes I have. Anybody have any ideas?
thanks

giga drain is an egg move and illegal with chlorophyll (male-only DW ability). you'll have to use energy ball :/
